The results of modeling of rock mass stress state in the vicinity of large open pit mine using finite-elements method are represented. The model allows to take into account the influence of large-scale fractures. The initiation of boundary conditions is based on the results of determination of stress parameters in situ. The locations of risk areas near the slope are defined.
Methods of earth's surface and underground light-distance-measurements poligons for geodynamics monitoring in apatite output in Khibin mountains are described.
